Jackson's death marked the first LAPD homicide investigation of 2014, department officials said.

Like in many major U.S. cities, the number of killings continued to drop in Los Angeles in 2013. Final figures were not yet available, but as of Dec. 28, the city saw 250 homicides — a 16% decrease from the year before — and was on pace to see the fewest recorded since 1966.
